Google hosted its very first Android Dev Summit this week and put on a number of seminars and keynotes for developers to see and learn some of the newest and most useful ways to make use of its APIs, features and services. The Dev Summit kicked off at the Computer History Museum just a couple of days ago and now you can catch all 20 sessions hosted on YouTube.

Subjects ranged from making the best use of Android’s new permissions, secrets of success on the Play Store and best practices for notifications among many others. Dave Burke and Stephanie Cuthbertson were two of many Google developer chiefs who took stage during the summit and kicked it off with a look back at some of the early days of developing and how things have changed. We’ve come a long way since the pre-Android days where the only well-known platforms were Symbian, BlackBerry and Windows Mobile.

If you’re a developer, you’ll want to make sure you watch the videos especially if you didn’t catch any of the sessions in person. If you were there, or tuned in live and want a refresher, you’ll find the entire playlist of Android Dev Summit session videos embedded below:
